Title: Method of treating molten metal
IPC: C21C7/10
Filed: 1972-02-03
Abstract: 1368881 Treating molten metals ACIERIES REUNIES DE BURBACH-EICH-DUDELANGE S A 3 Feb 1972 [4 Feb 1971] 5197/72 Heading C7D Molten metal such as iron or steel are treated by passing the melt from container 5 to a treatment container 1 by injection of a gas, neutral or reactive into inlet tube 2 from a gas injector 4, the metal returning under gravity to container 5 through outlet tube 3. Treatment additives, or alloying elements may be added from a dosing container 9 or blown in with the gas at the base of tube 2. High melting additives may be fused by passing through a superheated slag on the surface of the metal in the container 1. The level of the metal in container 1 may be raised by passing gas under pressure into the enclosed space of container 5 through pipe 8. Mining may be aided by varying the flow of gas from injector 4, by varying the pressure of gas introduced through pipe 8 or, in use of the apparatus of Fig.1 (not shown) by raising and lowering the containers 1 and 5 relatively to each other. Reference is made to addition of magnesium for production of spheroidal graphite cast iron and to addition of lead or sulphides for producing free-cutting steels.

Abstract: 645,536. Automatic control systems for heated spaces. VAPOR HEATING CORPORATION. March 7, 1946, No. 5268. Convention date, April 16, 1945. Divided out of 645,472. [Class 38 (iv)] In a railway car heating system, as described in Specification 645,472, each car compartment is heated by a steam radiator with an on-off valve controlled by a thermostat in the compartment, and the main steam supply for the car passes through an on-off valve controlled by two parallel connected thermostats, which respond respectively to the outside and mean inside temperatures. As shown, each compartment is heated by a radiator 10 supplied with steam through the on-off valve G operated by solenoid K which is energized through the relay I by the thermostat H situated in the compartment. The setting of thermostat H is selected by means of the heating winding 19, the current through which may be manually adjusted by the potentiometer 20, or set to a fixed value; the differential of the thermostat is reduced by the passage of a further current through 19 upon the operation of relay I. The external and internal thermostats V, W are in parallel and control the relay X which effects the energization of the solenoid 18 to control the main steam supply valve, the latter being closed when the outside or mean internal temperature rises above 50‹ and 60‹ F. respectively. The relay 23 maintains setting of the thermostats constant against variations in supply voltage.

Abstract: 620,672. Lubricating thrust bearings. ENGLISH ELECTRIC CO., Ltd., and SEEWER, P. W. Feb. 26, 1946, No. 6006. [Classes 12 (i) and 12 (iii)] Circulation of oil through an oil-immersed thrust bearing is effected by impeller vanes provided on the rotary member and located coaxially within the stationary member to serve as an axial - flow pump. As shown, in sectional elevation in Fig. 1 and twopart sectional plan Fig. 2, a vertical shaft 43 of a large hydro-electric generator is supported by its collar 31 of cast-iron being rotatively borne on Michell pads 29 of chilled cast iron, tiltably held on their part-spherical seatings 29a in a cast-iron base ring 20 by bolts 21, 22 with strong spring washers 41, 42 beneath the bolt heads, the bolts having clearance with the bores through the base ring 20 and being arranged in the same radial plane through the shaft axis and the centre of the part-spherical seatings 29a. The cast-iron base ring 20 has a spherical seating 20a on a steel ring 26 upstanding from the bottom of the enclosing oil chamber, such ring 26 being slotted at its bottom to provide passageways for the oil to a central space in which depends from the rotary collar 31 a cylindrical member 37 provided with impeller vanes 38 which serve as an axial-flow pump to circulate the oil through the bearing ; directing baffles 47, 25, 35-36, 48 cause the circulating oil to pass through a nest of cooling tubes 34 before its return to the bearing region. The rotary thrust collar 31 is.also radially supported by a number of Michell pads 17 through which the oil is directed and may have radial ducts 31a which give a radial flow pump action to stimulate the oil flow of the axial-flow pump vanes. The rotary thrust collar 31 is fixed to a steel ring 30 which is keyed to the shaft 43 and held axially by bolting to a divided ring 10 fitting a groove 43a on the shaft. An inside sleeve 24 close to the shaft but fixed to the base 27 and so acting as inner wall of the oil chamber carries a flaring cup-piece 12 extending above the oil level into a recess in the rotary ring 30 which has breather ducts 30a opening above the cup-piece 12. Specification 620,740 is referred to.

Abstract: 574,862. Welding. MALLORY METALLURGICAL PRODUCTS, Ltd. March 12, 1945, No. 6094. Convention date, March 11, 1944. [Class 83 (iv)] A water-cooled, tubular resistance, welding electrode holder 10 carried by an arm 13 of the welding machine and provided with an electrode 22 having a recess 24 for the circulation of cooling fluid supplied by an inlet tube 21 entering the recess, has means at the discharge end of the inlet tube for increasing the velocity of flow within the recess to increase the amount of heat withdrawn from the electrode. For this purpose, the discharge end of the tube 21 is formed with a portion of greatly reduced diameter in the form of a constricted throat 26. This may be followed by a slightly divergent outlet nozzle 27 provided with rounded or bead-shaped edges to avoid resistance to flow and to preclude the possibility of the fluid breaking away from the confining walls at high speed. The hose attachment member 15 in which the tube 21 is screwed and which has integral nipples 18, 19, is attached to the holder by a nut 17. In a modification, the tube 21 is formed with a thickened terminal portion 30 shaped to define a contracting conical entrance channel 31 of about 21 degrees, a constricted throat section 32 and an annular expanding conical outlet channel 33 of about 5 to 7 degrees located between the corresponding outer surface of the inlet tube and the inner surface of the recess 24. In addition to rounding at 34 the end of the inlet tube to facilitate reversal of the liquid flow without producing turbulence, eddy currents, &c., the end of the recess is formed with heart-shaped rotation surfaces 35 to provide an inward projection 36 widening from the top to the bottom and merging into the side walls of the recess to constrain the fluid to flow outwardly in all directions radial to the axis and then backwardly in the recess about such tube. The electrode may be used particularly in welding aluminium, magnesium and zinc and also tin- and zinc-coated steels and terne plate and copper alloys.

Locking nuts.-A pair of washers &c., one of which is arranged to grip the work and the other the nut, are arranged between the nut and the work, and a connexion between the washers is arranged so that relative rotation of the washers can occur in one direction only. The invention is shown as applied to locking a pair of nuts 11, 12 against relative rotation. One of the washers 13, Fig. 5, is cut-away about the periphery forming projections 16 provided with radial teeth 17. The other washer 14, Fig. 7, is dished and also has cut-away portions forming projections having teeth. In addition, it is provided with a struckup resilient tongue 20 which projects on the opposite side of the washer from the teeth 17. The washers are assembled with the smooth sides in contact and with the tongue 20 engaging one of the notches 15 in the washer 13. Upon screwing down the nut 11, the teeth on the washers embed in the nuts and the tongue 20 acts as a ratchet to allow relative movement of the washer 13 and nuts 11 and the washer 14 and nut 12 in one direction and prevent it in the reverse direction. The tongue 20 projects beyond the periphery and can be operated to permit the nuts to be unscrewed. In a modification, the dished wa.sher 14 is provided with teeth projecting into the aperture so that when it is crushed, the teeth bite into the bolt.
